Foldable stroller

ABSTRACT

A stroller has a retractable canopy frame, which can be accomplished by mounting the canopy frame to a seat support frame extending rearwardly beyond the pivoting connection to the stroller rear legs. The stroller also has a remote hinge-lock actuator incorporated into an upper tray connected between the push arm portion of the stroller frame. The stroller also has an infant carrier securing mechanism that allows the infant car carrier to be attached to the stroller and provide at least two tilt positions.

BACKGROUND

Foldable strollers, such as disclosed in U.S. Pat. No. 5,511,441 issuedto Arai; U.S. Pat. No. 5,181,735 issued to Onishi; U.S. Pat. No.4,953,887 issued to Takahashi, et al.; and U.S. Pat. No. 6,155,740issued to Hartenstine, have an articulated stroller frame that allowsthe stroller to fold from its use configuration to its collapsedconfiguration. These strollers include soft goods made of fabric, suchas a seat, back support, canopy, storage basket, etc., covering parts ofthe stroller frame. The back support can be movably configured between asitting position and a recumbent or lying position. These strollers alsohave left- and right-side hinge locks, between the respective left- andright-side push arms of the handlebar frame and the left- and right-siderear legs, to maintain the stroller in the operating configuration.

In such strollers, and other foldable strollers, the canopy frame or bowis typically attached to the push arms or the hinge locks. Consequently,the position of the canopy frame, relative to the push arms, remainsfixed at all times, between its open position and its closed position.When the stroller is folded, the canopy frame is at its closed position.But since the canopy frame position is fixed relative to the push arms,if a relatively large canopy is used, the canopy frame can protrudebeyond the handlebar. Particularly since a larger canopy is desirable toprotect infants from exposure to sunlight, the stroller can becomebulkier. Accordingly, there is a need for a stroller that can be mademore compact, particularly with the use of a larger canopy.

Further, it is desirable for the stroller to have ergonomically correcthandlebar, which typically is the cross bar member extending across thepush arms, for comfort and control. For added comfort to the caretaker,the handlebar angle can be adjusted relative to the push arms, asdisclosed, for example in U.S. Pat. No. 5,184,835 issued to Huang andU.S. Pat. No. 5,056,805 issued to Wang. Including such an adjustablehandlebar, however, makes it more difficult to provide a remotehinge-lock actuator on the handlebar, which typically needs a Bowdencable or similar arrangements to allow for the handlebar to rotatewithout actuating the hinge locks. In this respect, U.S. Pat. No.5,775,718 discloses a simple, cable operated remote hinge-lock actuatorpositioned adjacent to the handlebar. It would be desirable toincorporate a simple cable-operated remote hinge-lock actuator into theexisting structure.

Moreover, it would be desirable for the stroller to carry an infant carcarrier. While many different configurations for that purpose have beencontemplated, there still remains a need for a stroller that isconfigured to secure an infant car carrier in two or more reclined ortilted positions.

The present invention addresses these needs.

SUMMARY

The present invention is drawn to a stroller. According to one aspect ofthe present invention, the stroller can have a retractable canopy, whichcan be accomplished by mounting the canopy frame to a seat support frameor basket frame extending rearwardly beyond the pivoting connection tothe stroller rear legs.

Referring to FIGS. 1 and 2, the stroller frame 10 can have the basicfundamental frame configuration, similar to the ones identifiedpreviously in U.S. Pat. Nos. 6,155,740; 5,511,441; 5,181,735; and4,953,887, the disclosures of which are incorporated herein byreference. The stroller frame 10 according the present inventionincludes a handlebar frame 20, legs 30R, 30L, 40R, 40L, a passengersupport or frame 50, a tray assembly 60, and a pair of hinge locks 70.In the drawings, a letter “P” or “Px” (where x represents a number)designates a pivotal connection, a pivot, or pivotal mount, or anyconventional pivoting configuration, which can include pins, shaft,bolt, rivet, bearings, etc.

The handlebar frame 20 comprises a handlebar 22 and right and left pusharms 24R, 24L (collectively 24) extending from the handlebar 22. Thehandlebar 22 and the push arms 24 form a generally U-shaped frame. Thehandlebar 22 can be ergonomically configured for comfort, such asdescribed in U.S. Pat. Nos. 5,454,584 and 5,605,409 issued to Haut, etal., the disclosures of which are incorporated herein by reference. Thehandlebar frame 20 can include an angle adjuster 200 for pivotallypositioning the handlebar 22 relative to the push arms 24. The inneroperative workings of the angle adjuster is omitted for brevity,particularly since any known angle adjuster can be used, such as theones disclosed in aforementioned U.S. Pat. No. 5,184,835 issued to Huangand U.S. Pat. No. 5,056,805 issued to Wang, the disclosures of which areincorporated herein by reference. In the present embodiment, the angleadjuster 200 is adapted to provide a greater rotation capability so thatthe handlebar can be flipped over close to the push arms 24, as shown inphantom in FIG. 3.

The legs 30R, 30L, 40R, 40L can be described in terms of front legs 30,which include a front right (FR) leg 30R and a front left (FL) leg 30L,and rear legs 40, which include a rear right (RR) leg 40R and a rearleft (RL) leg 40L. Each leg 30R, 30L, 40R, 40L has a lower end to whichat least one rotatable wheel W is mounted. As shown, the front legs 30each can have a pair of rotatable front wheels WI, W2 (collectively FW).The rear legs 40 can be reinforced with a cross brace 45, which extendsbetween the rear wheels RW, above the rear wheel axle X. Similarly, thefront legs 30 can be reinforced with a cross brace 35 (hidden inside thefoot rest F) extending between the front wheels W.

The passenger support 50 includes a substantially U-shaped seat supportframe 52. A back support (not shown), which can comprise a soft good(fabric) or frame type with a reclining latch (not shown), can beconnected to the seat support frame 52. The seat support frame 52 has across arm 52C joined to left and right arms 52L, 52R. The seat supportframe arms 52L, 52R are pivotally mounted to the respective front legs30L, 30R at pivots P1, and are pivotally mounted to the hinge locks 70at pivots P2, as better illustrated in FIG. 2. The hinge locks 70 arefixedly mounted to the rear legs 40. Accordingly, the seat support framearms 52L. 52R are operatively connected pivotally to the rear legs 40.The support 50 can further include a seat 50S secured to the seatsupport frame arms 52L, 52R.

A portion of the seat support frame 52 protrudes beyond the pivotingconnection P2 of the rear legs 40 (or the hinge locks) to the supportframe arms 52L, 52R, as shown in FIG. 2. A storage basket or the like(not shown) can hang from the seat support frame 52, and hence sometimesreferred to as a basket frame, for storing various sundry items,including diapers, bottles, blankets, bibs, and other child-relateditems.

The tray assembly 60, which can have a U-shaped configuration as shownin FIG. 1, comprises a tray 62, and left and right side arms 64L, 64R(collectively 64) pivotally connected respectively to the left and rightpush arms 24L, 24R at pivots P3. Specifically, referring to FIG. 1, thedistal (rear) end of each of the side arms 64 has a pair of spaced ears64E or the like that are spaced apart to receive the respective push arm24L, 24R, and are held pivotally together with pivots P3. The tray 62,which can have one or more cup or container holding compartments 62C,can be either fixedly formed with the side arms 64, detachably mountedto the side arms 64, such as disclosed in U.S. Pat. No. 4,856,809, thedisclosure of which is incorporated herein by reference, or pivotallyconnected or hinged to one side of the side arms 64L, 64R,while theopposite side can be latched to the other of the side arms 64L, 64R. Inthe third option, the tray 62 can also be rotatably mounted to the oneside arms 64L, 64R, thus creating two axes of rotation. The tray 62 canbe opened (pivoted along one substantially extending axis) and rotatedabout a second axis to tuck the tray 62 alongside the respective frontlegs 30R, 30L. Moreover, any conventional attaching means can becontemplated for detachably or movably attaching the tray 62 to the sidearms 64.

The front and rear legs 30, 40 are pivotally mounted to the trayassembly 60. Specifically, the upper end of the front and rear legs 30,40 are pivotally mounted to the. respective side arms 64 with pivots P4,P5, respectively.

The hinge locks 70 (left 70L, right 70R) pivotally mount the handlebarframe 20 to the rear legs 40 at pivots P6. The hinge locks 70 can be anyconventional hinge lock for maintaining a fixed position between therear legs 40 and the handlebar frame 20 when locked, and for allowingpivotal motion therebetween when unlocked. For instance, the left andright hinge locks 70L, 70R each can be fixedly attached to andpositioned between the ends of the respective rear leg 40L, 40R. Theends of the respective left- and right-side push arms 24 can bepivotally mounted to the respective hinge locks 70 at pivots P6 (whichcan share common pivots with pivots P2). To lock the handlebar frame 20to the rear legs 40, each hinge lock 70 can include, for instance, aplunger or the like (not shown) that is movably mounted inside thehandlebar frame 20, or a latch (not shown) that is pivotally mounted tothe handlebar frame 20. The plunger can be biased inwardly into therespective hinge lock 70L, 70R or the latch can be biased to hook onto afixed portion of the respective hinge lock 70L, 7 0R to lock thehandlebar frame 20 to the rear legs 40. Alternatively, the hinge lock 70can be configured as disclosed in previously mentioned U.S. Pat. No.6,155,740 issued to Hartenstine, or U.S. Pat. No. 5,110,150 issued toChen, the disclosures of which are incorporated herein by reference.

A pair of remote actuating members 100L, 100R (collectively 100) or thelike can be operatively connected to the hinge locks 70, such as with acable or rod (not shown). Each of the left and right actuating members100L, 100R are slidably mounted to the respective left and right pusharms 24L, 24R. Pulling each of the remote actuating members 100L, 100Rupwardly along the respective left and right push arms 24L, 24R actuatesthe respective hinge lock 70L, 70R, e.g., moves the plungers upwardlyinto the push arms 24 or disengage the latch.

To unlock the stroller frame 10 from the operating position to thefolded position, the operator can slide both remote actuating members100 along the push arms 24 in the direction of arrow UN (see FIG. 2),which unlocks the hinge locks 70. Once the hinge locks 70 are unlocked,the stroller can be folded, for example, by pivoting the tray assembly60 about the handlebar frame 20, in the counterclockwise direction CCW(FIG. 2), which raises the tray 62 upwardly to the folded position (FIG.3), while lowering the cross arm (distal end portion) 52C of the seatsupport frame 52.

Upper Tray/Hinge Lock Actuator

Referring to FIG. 4, the stroller also can include a one-hand hinge-lockactuator 110, which is connected to the remote actuating members 100.According to one aspect of the present invention, the hinge-lockactuator 110 can be formed with an upper tray 120, which is connected tothe handlebar frame 20. The upper tray 120 comprises at least onerecessed compartment, such as a cup or container holding recess 122. Theillustrated embodiment shows two cup or container holding compartments122 and a through-hole 124, which permits the operator's hand or fingersto be inserted therethrough.

The tray 120 can be mounted to the push arms 24 or to the angle adjuster200 about pivots P7. Specifically, the angle adjuster 200 can have afixed pivot member 202L, 202R (collectively 202) extending from eachupper end of the left and right push arms 24L, 24R and a movable pivotmember 204L, 204R (collectively 204) extending from each lower end ofthe handlebar 22. The fixed pivot members 202 are positioned facing eachother, i.e., positioned inwardly of the respective movable pivot members204. The fixed pivot members 202 can have tracks, sockets, or anymechanical connectors that can receive complementary mating parts formedon the left and right sides 120L, 120R of the tray 102.

The remote hinge-lock actuator 110 comprises a handle 112 and left andright linkage assemblies 130L, 130R (collectively 130). The handle 112is mounted for a movement between an actuated or pushed position, whichpulls up the actuating members 100 to release the hinge locks 70, and anon-actuated or locked position, where the actuating members 100 are attheir normal, down position (hinge locks 70 remain locked). The handle112 can be biased toward the non-actuated (locked) position, and caninclude finger contours 112F. Either hand of the operator can beinserted into the through-hole 124 so that the fingers loop around thefinger contours 112F. To actuate or release the hinge locks 70, theoperator presses or pulls up the handle 112 with his or her fingers.

Still referring to FIG. 4, the right and left linkage assemblies 130L,130R are substantially identical, mirror images of each other. Each ofthe right and left linkage assemblies 130L, 130R comprises a crosslinkage 132 connected to a push rod 134. The cross linkage 132 issubstantially U-shaped, having a first arm 132F and a second arm 132Sspaced from the first arm 132F and joined by a third arm 132T. The firstarm 132F is connected to one side of the handle 112 and the second arm132S is pivotally connected to the push rod 134. The third arm 132T ispivotally journaled to the underside of the tray 120. Actuating thehandle 112 simultaneously rotates the left and right cross linkages 132in the direction of the arrow U (pivots toward the upper side of thetray 120). One end of the push rod 134 is pivotally connected to thefree end of the second arm 132S, and the other end is pivotally securedto the respective actuating members 100L, 100R. In this respect, each ofthe actuating members 100L, 100R has a push rod receptacle 134Rconfigured to receive and hook (or latch) onto the respective push rod134. As the operator pushes the handle 112, both the left and rightcross linkages 132 rotate, which pull up the respective left and rightpush rods 134, and thus the actuating members 100L, 100R and allow thehandlebar frame 20 to pivot relative to the hinge locks 70.

Canopy Frame

According to another aspect of the present invention, the strollerincludes a canopy support rod or frame 80 attached to the seat supportframe or basket frame 52 at pivots P8. The frame 80 comprises one ormore substantially U-shaped canopy bows 82 (only one shown) that supporta canopy and pivotally or movably attached to the set support frame 52.In this respect, any conventional bow mounting system can be used. Thecanopy frame 80 can be moved between a use position (solid in FIG. 2)for shading a passenger and a stow position (phantom in FIG. 2) where itis pulled close to the handlebar frame, away from the passenger. Thecanopy bow(s) 82 is pivotally attached at the pivots P8, which islocated on the portion 52B of the seat support frame extending beyondthe pivots P2, P6. In this respect, the canopy bow 82 can have outwardlyextending bulge 84 to provide clearance for the push arms 24.

When the stroller is being folded from the operating position shown inFIG. 2 to the folded position shown in FIG. 3, the distal end (cross arm52C) of the seat support frame 52 rotates counterclockwise CCW, towardthe rear wheels RW, while the handlebar frame 20 rotates clockwise CW.This lowering action of the support frame 52 retracts the bow 82downwardly and automatically positions the bow 82 close to the handlebarframe 20. It should be noted that the canopy 4 can be mounted around thehandle frame 20. Thus, moving the handlebar frame 20 pivots the canopyframe 80 to the position shown in phantom when the stroller is folded.But because the canopy frame 80 is retracted when the stroller is fullyfolded (FIG. 3), the bow 82 is tucked in between the handlebar frame 20and the tray assembly 60.

The area (crest) 86 of the bow furthest from the pivots P8 can belocated higher than the handlebar 22, as shown in FIG. 2 when thestroller is in the operating position. Nonetheless, because of thepresent unique mounting of the canopy frame 80, the crest 86 of the bowcan extend well below the handle bar 22, as shown in FIG. 3. In thisrespect, it is preferable for the crest 86 to be positioned inwardlyfrom the front end of the tray to protect the canopy 4.

It is further desirable to make the stroller as compact as feasible whenit is folded. According to the present invention, the handlebar 22 ismade foldable about the pivots P8 as shown in phantom in FIG. 3. Bypivoting the handlebar 22 in the counterclockwise direction, thehandlebar 22 is no longer the highest or longest point of the foldedstroller, and the overall length of the folded stroller can beconsiderably reduced.

Infant Carrier Mount

FIGS. 5 and 6 illustrate the present stroller 1 with an infant carrier300 mounted thereto. According to another aspect of the invention, thestroller 1 provides at least two tilt positions, reclined and upright,while the infant carrier is rearwardly facing. In this respect, theinfant carrier 300 can be mounted to the tray as described in U.S. Pat.No. 6,070,890, the disclosure of which is incorporated herein byreference. That is, the front tray 62 can have a notch or the like (notshown) that can latch onto a retractable catch or the like (not shown)formed on the underside of the infant carrier. The handlebar frame 20carries infant carrier securing mechanism 320, which comprises aplurality of abutments or stops 322 (322U, 322L) rotatably mounted tothe left and right push arms 24L, 24R. The stops 322 are rotatablebetween an engage position shown in FIG. 1 and a disengage positionrotated away from the engage position. The present embodiment has fourstops, a pair of lower stops 322L and a pair of upper stops 322U.

Referring to FIG. 5, the carrier 300 is seated so that it is rearwardlyfacing (facing the caregiver) and is positioned in an upright position.In this position, the lower stops 322L are rotated to the engageposition to abut the upper front left and right sides 300S of the infantcarrier. The lower stops 322L are rotated toward each other after theinfant carrier 300 is placed in position. In this position, the frontpart of the infant carrier 300 is supported by the seat support 50S (andthe associated seat cushion 2 and the lower stops 322L) and the lowerstops 322L confine the infant carrier from being lifted upwardly.

Referring to FIG. 6, to position the infant carrier in the more reclinedposition, the lower stops 322L are rotated so that they face each other,as shown in FIG. 1. The infant carrier 300 rests on the front tray 62and the lower stops 322L. Once the infant carrier 300 is positioned, theupper stops 322U are rotated so that they abut against the upper surfaceof the upper front left and right sides 300S of the carrier. The lowerstops 322L prevent the infant carrier 300 from moving downwardly to theseat 2 and the upper stops 322U prevent the infant carrier 300 frombeing lifted upwardly. This thus keeps the carrier locked onto thestroller.

Given the disclosure of the present invention, one versed in the artwould appreciate that there may be other embodiments and modificationswithin the scope and spirit of the present invention. Accordingly, allmodifications attainable by one versed in the art from the presentdisclosure within the scope and spirit of the present invention are tobe included as further embodiments of the present invention.
